Abstract
Abstract The lifting lever of a mechanism for lifting a large window of an automotive vehicle is provided with two fixedly connected arms pivoted on the lever. The lever is turned by a segment gear on one end, and its other end engages the window to be lifted. One of the arms also engages the window and the other is guided on the body of the vehicle on which the lifting lever is mounted. The arms are stampings of flat bar stock having at their inner ends circular shoulders rotatably received in a circular opening of the lever which they enter from opposite sides. They are connected in the opening of the lever by a rivet and interengaged projections and recesses.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
291 words
In a lifting mechanism for a window in the body of an automotive vehicle, the mechanism including a mounting member adapted to be mounted on said body, a lifting lever, first pivot means securing said lever to said member for pivoting movement about a first axis, first and second elongated arms, second pivot means securing respective first longitudinally terminal portions of said arms to said lever for joint pivotal movement of said arms relative to said lever about a second pivot axis spaced from said first axis, engaging means on respective second longitudinally terminal portions of said arms remote from said second axis and on a terminal portion of said lever spaced from said second axis in a direction away from said first axis, and a plurality of guide means respectively associated with said engaging means for movably securing the engaging means on said lever and on said first arm to said window, and for movably securing the engaging means on said second arm to said body, the improvement in said second pivot means which comprises: a. a projecting shoulder defining a circle on the first terminal portion of each of said arms about said second axis, 1. said lever being formed with an opening therethrough receiving said shoulders in conforming engagement for rotation of said first terminal portions about said second axis, 2. said arms being offset from each other in the direction of said second axis and said shoulders entering said opening from opposite axial directions; and b. fastening means axially extending in said opening and fixedly connecting said first terminal portions, said fastening means including an axial projection on one first terminal portion remote from said second axis and engaging an opening in the other first terminal portion.

In a lifting mechanism for a window in the body of an automotive vehicle, the mechanism including a mounting member adapted to be mounted on said body, a lifting lever, first pivot means securing said lever to said member for pivoting movement about a first axis, first and second elongated arms, second pivot means securing respective first longitudinally terminal portions of said arms to said lever for joint pivotal movement of said arms relative to said lever about a second pivot axis spaced from said first axis, engaging means on respective second longitudinally terminal portions of said arms remote from said second axis and on a terminal portion of said lever spaced from said second axis in a direction away from said first axis, and a plurality of guide means respectively associated with said engaging means for movably securing the engaging means on said lever and on said first arm to said window, and for movably securing the engaging means on said second arm to said body, the improvement in said second pivot means which comprises: a. a projecting shoulder defining a circle on the first terminal portion of each of said arms about said second axis, 1. said lever being formed with an opening therethrough receiving said shoulders in conforming engagement for rotation of said first terminal portions about said second axis, 2. said arms being offset from each other in the direction of said second axis and said shoulders entering said opening from opposite axial directions; and b. fastening means axially extending in said opening and fixedly connecting said first terminal portions, said fastening means including an axial projection on one first terminal portion remote from said second axis and engaging an opening in the other first terminal portion.
Claim 3
Dependent Claim
67 words
said arms being offset from each other in the direction of said second axis and said shoulders entering said opening from opposite axial directions; and b. fastening means axially extending in said opening and fixedly connecting said first terminal portions, said fastening means including an axial projection on one first terminal portion remote from said second axis and engaging an opening in the other first terminal portion.
Claim 4
Dependent Claim
67 words
said arms being offset from each other in the direction of said second axis and said shoulders entering said opening from opposite axial directions; and b. fastening means axially extending in said opening and fixedly connecting said first terminal portions, said fastening means including an axial projection on one first terminal portion remote from said second axis and engaging an opening in the other first terminal portion.
Claim 5
Dependent Claim
31 words
In a mechanism as set forth in claim 1, the axial height of each of said shoulders being greater than one half the thickness of said lever in said opening thereof.
Claim 6
Dependent Claim
28 words
In a mechanism as set forth in claim 1, said fastening means further including a rivet centered in said shoulders and axially passing through said first terminal portions.
Claim 7
Dependent Claim
49 words
In a mechanism as set forth in claim 1, the first and second longitudinal portions of each arm and said shoulder on the first longitudinal portion thereof constituting a unitary body, and said axial projection being an integral part of the unitary body of said one first terminal portion.
Claim 8
Dependent Claim
72 words
In a mechanism as set forth in claim 4, said lever having an inner circumferential wall in said opening thereof, said wall slidingly engaging said shoulders during rotation of said arms relative to said lever about said second axis, each arm being formed with a receptacle for a lubricant contiguously adjacent said wall, said receptacle being offset from the shoulder of said arm in a direction radially away from said second axis.
Claim 9
Dependent Claim
75 words
In a mechanism as set forth in claim 1, each arm consisting of flat bar stock of approximately uniform thickness in the direction of said second axis and formed with a substantially circular depression in one wide longitudinal face of said first terminal portion so that said first tErminal portion is approximataly dish-shaped, the bottom of said dish shape in the other wide face of said first terminal portion being bounded circumferentially by said shoulder.
Claim 10
Dependent Claim
36 words
In a mechanism as set forth in claim 6, said second terminal portions of said arms being offset from the corresponding first terminal portions in opposite axial directions, said first and second axes being substantially parallel.
Claim 11
Dependent Claim
36 words
In a mechanism as set forth in claim 6, the bottom of the dish shape of each first terminal portion being spaced axially from the bottom of the dish shape of the other first terminal portion.
